Abstract
The utility model relates to a crane which can move on the ground and is used for hoisting objects. The mobile crane is disclosed for solving the problem that the mobile crane with smaller area of a base (2) is unstable to grasp the ground, the mobile crane comprises the base (2) and a machine rod (1) which is arranged on the base (2) and used for mounting a hoisting part, and the mobile crane is characterized in that the base (2) is further connected with an extended support leg (3) which expands/retracts towards the outer side of the base (2).
Description
Technical field
The utility model relates to the loop wheel machine that can move on the ground.
Background technology
The machine bar height of old-fashioned portable loop wheel machine is fixed, and generally should not machine bar design De Taigao then be taken up room greatly because the machine bar is too high, is not easy to move and deposit.This has just limited the height that portable loop wheel machine can lift by crane.
Portable loop wheel machine can move on the ground, moves different positions to and carries out lifting operation.Lifting part is located at machine masthead portion, and center of gravity is higher, and for the ease of moving, the area of its base is done smallerly, and this unstable with just causing grabbing of portable loop wheel machine, topples over easily.If adopt the bigger base of area, occupation space is bigger when then depositing, and moves inconvenience.This has also limited the height that portable loop wheel machine can lift by crane.
Technique scheme is only on probation at internal implementation, and is externally not open.
The utility model content
The utility model is intended to solve the less portable loop wheel machine of base area and grabs the unstable problem in ground.
Provide portable loop wheel machine for this reason, comprise base and be located at the machine bar that is used to install lifting part on the base, it is characterized in that base also is connected to the overhanging feet that opens/regain towards chassis outer side.
After moving to control position, overhanging feet is opened towards chassis outer side, just can increase a plurality of distances of grabbing intersite, grab ground more firm, be difficult for toppling over.Work finishes when moving and depositing, and overhanging feet is regained, and is convenient to move, and it is little to take up room.
Description of drawings
Fig. 1 is the scheme drawing that overhanging feet stretches out towards chassis outer side.
Fig. 2 is that overhanging feet is retracted in the scheme drawing on the base.
Fig. 3 is a machine bar contraction state scheme drawing.
Fig. 4 is that the machine bar stretches out view.
The specific embodiment
Being connected and can changing between base 2 and the overhanging feet 3: base 2 end faces or bottom surface are provided with guide rail from the inside to the outside, and overhanging feet 3 moves protuberate basic unit 2 outsides along guide rail and also can realize opening.
The machine bar 1 of portable loop wheel machine can adopt expansion link, can shrink (as Fig. 3) or stretch out the adjusting that (as Fig. 4) realizes height, adapts to the height of suspended object.When machine bar 1 extend out to state as Fig. 4, preferably overhanging feet 3 is opened to state as Fig. 1, topple in order to avoid center of gravity is too high.Work finishes when moving and depositing, and machine bar 1 preferably shrinks, and is convenient to move, and it is little to take up room.
The cooperation of overhanging feet 3 and expansion link has thoroughly been removed the sling height design-calculated has been limited.
Moving generally of base 2 realized by the pulley that is contained in its bottom, or moved by manpower.
During statement quantity, " many " as herein described are meant more than or equal to two.
Claims (4)
1. portable loop wheel machine comprises base (2) and is located at the machine bar (1) that is used to install lifting part on the base (2), it is characterized in that, base (2) also is connected to the overhanging feet (3) that opens/regain towards base (2) outside.
2. according to the portable loop wheel machine of claim 1, described overhanging feet (3) has a plurality of towards different directions.
3. according to the portable loop wheel machine of claim 1 or 2, described overhanging feet (3) is hinged on base (2) outside.
4. according to the portable loop wheel machine of claim 1, its machine bar (1) is an expansion link.
